Good colutions to send data contains many random consecutive '+' characters in ESP-AT mode?

[amax0615]

Hello,

We have requirements to send data which possibly contains random consecutive '+' character bytes in ESP-AT pass-thru mode.
But the ESP-AT documents says "+++" in data will cause exit from pass-thru mode...
Any suggestions to send such kind of data safely and efficiently?
Thanks!

Hello amax,

i don't think it is a real issue, could you please take a look about +++ command:

https://docs.espressif.com/projects/esp ... -data-mode

In the second note, there is a timing issue. that is to say, if your +++ does not meet this timing requirement, +++ will be treated as the real data, other than a command.
